Adenoid cystic carcinoma (ACC) is a malignant neoplasm that arises within secretory glands. It rarely occurs in the lacrimal gland. Kidney metastases are very rare.
We report a case of a 76-year-old female patient treated with right radical nephrectomy because of the tumour mass of the right kidney. Well-circumscribed, firm, grey mass was found on the lower pole of the kidney. Histologically, tumour was considered to be ACC. Retrospective history data showed ACC of the lacrimal gland surgically treated 14 years before with metastasis to the lung operated seven years before. Our diagnosis was metastatic ACC to the kidney.
ACC has a remarkable capacity for recurrence. To our knowledge, in the English-speaking area (PubMed), 10 cases of ACC metastatic to the kidney have been described to date, and this is the second reported case of kidney metastasis from primary lacrimal ACC.
腺样囊性癌（ACC）是一种起源于分泌腺的恶性肿瘤。它很少发生在泪腺。肾脏转移非常罕见。
我们报告了一例 76 岁女性患者，因右肾肿瘤接受了根治性右肾切除术。在肾脏下极发现一个边界清楚、质地坚硬的灰色肿块。组织学上，肿瘤被认为是 ACC。回顾性病史数据显示，14 年前曾接受过泪腺 ACC 的手术治疗，并有肺转移，7 年前曾接受过手术治疗。我们的诊断是转移性 ACC 至肾脏。
ACC 具有显著的复发能力。据我们所知，在英语地区（PubMed），迄今为止已经描述了 10 例 ACC 转移至肾脏的病例，这是第二例原发性泪腺 ACC 转移至肾脏的病例报告。
